Description

Technical Field

[0001] This utility model relates to the field of coal mine drill pipe technology, and in particular to a coal mine drill pipe that can be quickly loaded and unloaded. Background Technology

[0002] Drill pipes are an indispensable key component in underground drilling operations in coal mines. Their function is to transmit power from the drilling equipment to the drill bit, while also undertaking important functions such as conveying drilling fluid (or other flushing media) and removing drill cuttings. They play an important role in geological exploration, gas extraction, coal seam water injection, and roadway support in coal mines. Drill pipes that can be quickly loaded and unloaded can greatly shorten loading and unloading time, improve the efficiency of drilling operations, and thus accelerate the progress of the project.

[0003] Operators manually or with the aid of auxiliary tools align the male connector (with a protruding thread at one end) of the drill pipe with the female connector (with an internal thread) on the drill rig spindle, ensuring that their central axes coincide. After alignment, torque is slowly applied to tightly engage the male and female connectors through the threads, thus completing the loading and unloading of the coal mine drill pipe.

[0004] In existing technologies, some quick-load-and-disassemble coal mine drill rods are assembled and disassembled using tools and threaded connections with nuts. Threaded connections inherently require multiple rotations to tighten or loosen. Even with the aid of tools, the cumulative operation time is still significant when multiple drill rods are operated continuously, leading to reduced work efficiency. Therefore, to address these shortcomings, a quick-load-and-disassemble coal mine drill rod is proposed to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Reference Figure 1 and Figure 5 This utility model provides an embodiment of a quick-loading and detachable coal mine drill rod, comprising a cylindrical coal mine drill rod 1 and a connecting column 6. The cylindrical coal mine drill rod 1 is used for coal mine drilling. A threaded opening 2 is provided on the outside of the cylindrical coal mine drill rod 1, allowing for better drilling. A connecting column 3 is fixedly connected to the top side of the cylindrical coal mine drill rod 1 by welding, thus providing support for the cylindrical coal mine drill rod 1. An auxiliary mechanism 4 is fixedly connected to the bottom inner wall of the connecting column 3, which adjusts its reaction force according to the softness of the soil. The auxiliary mechanism 4 includes a cylinder 41, which provides a drive source. The bottom side of the cylinder 41 is fixedly connected to the bottom inner wall of the connecting column 3, ensuring stable operation of the cylinder 41. A circular plate 42 is fixedly connected to the drive end of the cylinder 41, allowing the circular plate 42 to slide by activating the cylinder 41. Multiple rotating plates 43 are rotatably connected inside the circular plate 42. The circular plate 42 slides upward and then pushes multiple fastening plates 44 to rotate.

[0026] A fastening plate 44 is rotatably connected to the top of the rotating plate 43. The rotational force is transmitted to the fastening plate 44 via the circular plate 42, allowing it to slide. A fixing block 45 is fixedly connected to the top side of the fastening plate 44 by welding, providing support for the fixing block 45. A guide shaft 46 is slidably connected inside the fixing block 45, guiding the fixing block 45 to slide, and then guiding the fastening plate 44 to slide. The bottom side of the connecting post 6 is fixedly connected to the top side of the connecting post 3 by welding, providing support for the connecting post 6. The connecting post 6 is slidably connected to the outside of the multiple fastening plates 44, allowing the fastening plates 44 to slide stably due to the constraint of the connecting post 6. The outside of the multiple guide shafts 46 is fixedly connected to the inside of the connecting post 6 by welding, allowing the guide shafts 46 to provide stable guidance. The outside of the multiple fixing blocks 45 is slidably connected to the inside of the connecting post 6, allowing the fixing blocks 45 to slide stably due to the constraint of the connecting post 6.

[0027] Reference Figures 2-4A disassembly mechanism 5 is fixedly connected to the top side of the connecting column 6, which provides disassembly efficiency. The disassembly mechanism 5 includes a disassembly column 51, the bottom side of which is fixedly connected to the top side of the connecting column 6 by welding, thus providing support for the disassembly column 51. A reset assembly 52 is fixedly connected to the bottom inner wall of the disassembly column 51. The reset assembly 52 includes multiple springs 5201, the bottom ends of which are fixedly connected to the bottom inner wall of the disassembly column 51, ensuring uniform force distribution. A sliding ring 5202 is fixedly connected to the top of each spring 5201. The sliding ring 5202 slides and then compresses the springs 5201, allowing the springs 5201 to store elastic potential energy, which in turn applies a force in the opposite direction to the sliding ring 5202 for reset. The outer side of the sliding ring 5202 is slidably connected to the inner wall of the disassembly column 51, guiding its sliding motion. The disassembly post 51 has an internal sliding connection with a pressing ring 53, which allows the pressing ring 53 to slide stably due to the restriction of the disassembly post 51.

[0028] The top side of the sliding ring 5202 is fixedly connected to the pressing ring 53. Pressing the pressing ring 53 causes the sliding ring 5202 to slide. The outer side of the pressing ring 53 is slidably connected to the inner wall of the disassembly post 51, guiding the pressing ring 53 to slide. A fixing ring 54 is fixedly connected to the top side of the disassembly post 51 by welding, providing support for the fixing ring 54. A fixing rod 55 is slidably connected inside the fixing ring 54, allowing the fixing rod 55 to slide stably due to the constraint of the fixing ring 54. A connecting ring 56 is fixedly connected to the top side of the fixing rod 55 by welding, providing support for the connecting ring 56. The outer side of the pressing ring 53 is slidably connected to the inner wall of the connecting ring 56, guiding the sliding installation of the connecting ring 56.

[0029] Both ends of the fixing ring 54 are slidably connected to arc-shaped pillars 57, which allow the arc-shaped pillars 57 to slide stably due to the constraint of the fixing ring 54. The far ends of the two arc-shaped pillars 57 are slidably connected to the left and right sides of the inner wall of the pressing ring 53, respectively. The pressing ring 53 abuts against the two arc-shaped pillars 57, causing the two arc-shaped pillars 57 to slide towards the closer side. Side blocks 58 are fixedly connected to the front and rear sides of the arc-shaped pillars 57 by welding, thus providing support for the side blocks 58. A guide rod 59 is slidably connected inside the side block 58, guiding the side block 58 to slide. Limit openings 510 are provided on both the left and right sides of the fixing rod 55. The limit openings 510 are square. The outside of the arc-shaped pillars 57 is slidably connected to the inside of the limit openings 510, providing space for the arc-shaped pillars 57 to engage.

[0030] Working principle: When installing the drill pipe, first, the connecting ring 56 drives the fixing rod 55 to engage inside the fixing ring 54. At the same time, hold the pressing ring 53 and slide it downwards. This will drive the sliding ring 5202 to slide and compress multiple springs 5201. The resetting force of the springs 5201 is transmitted to the pressing ring 53 for resetting. When the pressing ring 53 slides until it no longer presses against the two arc-shaped pillars 57, the fixing rod 55 will press against the two arc-shaped pillars 57 and slide to the opposite side. After engagement is completed, release the tension on the pressing ring 53. The force of the spring 5201 returning to its original position is transmitted to the pressing ring 53 and abuts against the two arc-shaped pillars 57, so that the two arc-shaped pillars 57 can be engaged inside the two limiting openings 510, thereby completing the installation of the columnar coal mine drill rod 1. Conversely, when the pressing ring 53 slides down and no longer abuts against the two arc-shaped pillars 57, the guide shaft 46 is pulled down and then the fixing rod 55 slides and abuts against the two arc-shaped pillars 57, so that the two arc-shaped pillars 57 slide to the opposite side, thereby completing the quick disassembly of the columnar coal mine drill rod 1.

[0031] When working in soft rock formations, the cylinder 41 drives the circular plate 42 to slide upwards, which in turn pushes the four rotating plates 43 to rotate. Then, each of the four plates pushes a fastening plate 44 to slide. At this time, the four fastening plates 44 will slide to the opposite side and contact the soft rock formation, thereby increasing the contact area of ​​the drill rod and enhancing stability when working in soft rock formations.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
